Matt 14 - Harod was not 1 guy, it refers to a family, there were many by that name.

Mat 14:1 At that time Herod the tetrarch heard the news about Jesus,

Mat 14:2 and said to his servants, "This is John the Baptist; he has risen from the dead; and that is why miraculous powers are at work in him."

Herod was called "Herod the terarch." This means he was a Governor. Herod was Governor over a fourth part of the region. There were several Herod's in history. The name "Herod" actually speaks of a family. They are descendants of Herod the Great. Herod was paranoid concerning the death of John the Baptist. Herod thought that this Yehsua was John the Baptist back from the dead. Possibly he felt that John was coming back from the dead to get him. We now have a historic interlude while Matthew catches us up on what exactly happened to John and why.
